After writing a guide for the game's single-player campaign for IGN, I spent more time with the game--specifically online--so that I could produce a well-rounded review for the site. That full review is newly available right here:

It's just shy of 1400 words, which might be a longer read than some have in mind, so here's the short version: Section 8 is a pretty nice way to pass the time online if you had to sell your copy of Call of Duty 4 and you got a copy of Section 8 for free.

There's no doubt in my mind that Call of Duty 4 is the better game, but I do quite enjoy my time with Section 8. It's better than, say, Halo 3. Then again, what isn't better than Halo 3? The list is pretty short, I'd wager.
